Everything was going fine at my new school, but I was in for a
shock one day when I discovered the class president Rumi and my classmate
Natsuki having sex in the school infirmary! Not only that, it turned out that
Rumi was a futanari - a hermaphrodite with something between her legs I wasn't
expecting to see. That evening when I got home and got a call from Rumi to come
and meet her, I knew it couldn't be good - but the first thing she said was,
"Won't you join us?"According to her story she'd been a futanari from
birth, and because of this had an unquenchable curiosity regarding the ways of
sex. She'd gotten to the point where having Natsuki as a sex partner isn't
enough... she told me she was planning to train our classmate Shizuko as a sex
slave! Shizuko, a neat freak famous for her disike of her male classmates, had
let it slip to Rumi that she was secretly very curious about sex as well...

Faced with no other options, I had no choice but to accept
Rumi's request to join her and her comrades in their erotic schemes... and from
that moment I was bound to these cute and "ecchi" kitties in their
catgirl alliance!

Featuring multiple paths that range
from amorous romantic play to kinky "training" sex, animal girl
cosplay galore, and deviant themes from light bondage to exhibitionism, Cat Girl
Alliance is a cute and sexy romp through fantasy school life.
